M- my RAPHAL FNLON ODILE CHAUVIN AND REN ARNOUX, OF PARIS, FRANCE.

APLPARATUS FOB REGISTERING THE CONSUMPTION OF LIQUID FUEL.

Application filed December 17, 1907.

To all whom it may concm:

Be it known that we, RAPHAE'L FE'NLON ODILE CHAUVIN and REN ARNOUX, bothcitizens of the Republic of France and both of 186 Rue Championnet, inthe city of Paris, Republic of France, engineers, have invented anImproved Apparatus for Registering the Consumption of Liquid Fuel, ofwhich the following is a full, clear, and

exact description.

Our invention is an improvement in apparatus for registering theConsumption of liqid fuel, and consists i'n certain novel constructionsand combination of parts hereinafter described and claimed. v

The object of the invention is to provide a controlling apparatus forregistering the quantity of liquid fluid consumed by thermal motors, asfor example the quantity of zoo petrol consumed by an explosion engneand under conditions which will render raud inpossible.

' The apparatus consists essentially of a single acting pump, in whichthe piston is 5 normally moved toward the delivery end of *the pumpcylinder, by a counter balance,

and is returned positively through mecha-- nism connected with the motorshaft.

The admission port of the pump which is provided with a check valve, isin communication with the liquid fuel reservoir, and the delivery orexhaust port which is also provided with a check valve is connected withthe motor in which the liquid is used,

V as for instance the carbureter.

In addition a counter is provided which registers the lineardisplacement of the piston rod at each stroke the said displacenentbeing proportional to the quantity of liquid 40 uel received by themotor.

Referring to the drawings forming a part hereof, Figure 1 is alongitudinal section of the improvement. Fig. 2 is a plan view.

Fig. 3 is an elevation of a modified form of apparatus( Fig. 4 is asection on the line A-A of Fig. 3, and Fig. 5 is a rear view.

The embodiment of the invention shown in Figs. l and 2, comprises afluid tight box or casing a, in which the mechanism-is in` closed, thecasing being provided at one end with a *reduced portion a* forming apump body, in which a piston b moves, the piston.

being provided with a leather cup c, so arranged as to permit thepassage off -,-the fluid i when the piston is on its return stfoke, thatSpecification of Letters Patent.

is the cup faces toward the delivery end of the cylinder.

The outer end of the piston rod is received 1n a bushing (Z, integralwith the opposite end of the casing, and a spring k, encircles thebushing and the piston rod, being arranged between the end wall of thecasing and a collar or arm n on the piston.

One edge of the rod is provided with rack teeth q, which mesh with apinion 7', connected by a silent feed clutch s, with a crown wheel t,which crown wheel meshes with a counting device u, for registering thelnear displacement of the piston rod in the delivery direction, and awindow c is provided in the casing, for permitting observation of thecounter.

The spring 6 is the counter balance acting normally to force the pistontoward the delvery end of the pump, and the piston is moved n a reversedirection, by a. cam received on the shaft m, connected with the motorshaft, which cam bears against the friction roller on the collar or armn. The shaft m is provided with a pinion m' meshing'with an idler m,which meshes with a pinion o' connected with a revolution counter, theindications of which are read through a window t in the casing providedwith a A transparent covering.

A pipe e leads from the reservoir, and delivers to the casing, the saidpipe being provided with a check valve f, and with a needle valve z',and the pump chamber delivers to the motor through a pipe g, alsoprovided with a check valve h, and a needle valve j.

The mechanism shown in Fi s. 3 to 5 inclusive comprises a casing closeat its front by a glass a', secured in place by a frame a 9 connected tothe box by screws, and springs a are located in sleeves within thecasing, and bear against the glass, to insure a water tight joint. Agasket a is arranged between the 4 frame and the casing against whichthe glass bears, and an admission pipe e leads to the casin from thereservoir.

Within the box is arranged a pump oylinder 11 opening directly into thecasing at one of its ends, and communicating at its oposite end with apassage h communicating with the outlet ppe g, anda check valve h' isarranged in the passage.

The piston b, is constructed in the same manner as the piston a beforedescribed, and 10 is normally moved toward the delivery end of thecylinder by coil springs 76, which springs have their ends connectedwith a cross head n', on the outer end of the piston rod, b', thecentral portions of the springs passing over pulleys 10 at the-deliveryend of the pump.

The piston is moved in the opposite direction by a frction roller Zacting against the head 'ni', the friction roller being fixed to aplanetary pinion Z meshing with an internal gear 1 whose diameter istwice that of the ,pinioL The planetary pinion 1 is journaled on a diskZ keyed to a shaft 2 which shaft is provided with a worm wheel Z meshinwith a worm m on a shaft m', which is driven from the motor. The disk Zcarries twgopins l which are adapted to engage and operate a star wheel0', operating a revolution counter o.

It will be evident from the description, that as the disk l rotates, theplanetary pinion Z? will be revolved in a circle whose aXis is the shaftZ The internal' gear which is fixed, will rotate said pinion in areverse direction, thus movingthe friction roller Z horizontally and ina straight line.

The head n' connected with the piston rod b' is connected with a barrel7', by means of a steel band q winding upon the barrel.

- The barreldrives a pinion t in the direction of the arrow shown, beingconnected therewith by a silent feed clutch .9, and the pinion ttransmits the motion it receives to the peg wheel t', which connectswith and drives the counter u, the counter registering the lineardisplacement of the piston d.

To prevent retrograde movement of the counter while the clutch s is outof gear,

the axle t of the peg wheel carries a loosely mounted eccentric tnormally moved in a reverse direction by a spring t and the eccentriclooks the plate i during the reverse movement of the feed clutch. .Toprevent cutting of the shafts 2 and the gears Z and m', they rotate in abox o, containing oil.

The operation of the device is as follows:

` Normally the .body of the pump is filled with fuel, and 'the piston ateach revolu-- v the reservoir and the carbureter and is actuated by themotor. Moreover, the, indian; tions furnished by the counters o and u,may

be Compared to ascertain wlether the quan tity of fuel consumedcorresponds to the number of revolutions made by the motor.

The improvement also forms a feed pump for the liquid fuel permittng thereservoir containing the latter to be placed in any desired positionrelative to the apparatus.
